INCANDESCENT-ELECTRlC-LAMP HOLDER.

SPECIFICATION forming part of Letters Patent No. 613,248, dated November1, 1898.

Application filed November 5, 1897. Serial No. 657,461. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. COOK, J r., a citizen of the UnitedStates, residing at Bloomfield, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements inIncandescent-Electric-Lamp Holders; and I do hereby declare thefollowing to be a full, clear, and exact de scription of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

The object of my invention is to furnish an apparatus for securing anadjustable horizontally-suspended position for incandescent electriclamps. This object I have gained by constructing theherein-describedsuspensionframe, the main principle of which is the creation of anequilibrium by the horizontal movement made possible by my constructionof, respectively,the lamp-shade and my improved frame attached to thelamp.

In describing my invention I shall call attention to the accompanyingdrawings, wherein like letters of reference indicate corresponding partsin the different views.

Figure 1 shows a side view of an electric lamp having my improved frameattached; Fig. 2,a top view of Fig. 1; Fig. 3, a perspective view of myimproved frame detached from the lamp; and Fig. 4:, a different mode ofattaching the frame and the shade to each other, involving no departure,however, from my inventive principle.

In Fig. 1, A indicates myimproved frame, made of a simple piece of wireformed by two parallel-running strands H and H having at one end a loop13, secured around an insulating-bush O, which bush is screwed into theend of the socket D. At the other end a second loop or catch E isformed, which lies around the glass-smelting apex F of the bulb G.Sliding between these two parallel-running wire strands H and H whichform the frame A, is an equilibrium-guide L, composed of a disk M and ascrew-cut insulating-bush N, between whose head N and the said disk Mthe two strands 1-1 and H slide. Passing through the insulating-bushes Nand O is the lamp-cord 0, connected and acting in the customary mannerupon the lamp. If the lamp-shade (not shown in Figs. 1 and 2) is thenattached to the upper screw-cut part of bush N, it will be obvious thata horizontal equilibrium for the lamp, as suspended by the lamp-cord,will have been gained by means of the improved frame A, cooperating forsuch purpose with the thereto-attached lamp-shade and theabove-described intermediate elements.

In Fig. 4: I have illustrated a modification in the attachment of thesuspension-frameA to the lamp-shade P. The frame Ais, as described inconnection with Figs. 1 and 2, similarly attached by its two loops oreyes B and E to the bulb G and the socket D, and the insulating-bush N,having the cord 0 passing through it, is, as before, secured to thelampshade P. Furthermore, there are secured to the said shade P foureyelets, of which the two R and R, lying around the strand H, can onlybe seen. This what might be called indirect mode of attachment betweenthe shade P and my improved frame A will permit the use of any shape ofshade that may be desired. The manner in which the horizontalequilibrium is gained in this case is exactly the same as in the formercase by the relative adjustment laterally of the lamp and the shadethrough the medium of the frame, with this exception, that in theinstance of Figs. 1 and 2 the equilibrium was gained by sliding the bushattached to the shade back and forth in the frame A, whereas in theinstance of the construction shown in Fig. 4 the frame A is slid backand forth in the eyelets R and R, secured to the shade P, and theinsulatingbush is, as before, screwed into the shade, having thelamp-cord passing through it, but otherwise detached from frame A.

Various small details of construction may of course be altered from timeto time. It might, for instance, be found practical to have the strandII cut through at the point marked X as one method of slipping thelamp-cord in without disconnecting it when attaching the frame; but

What I especially claim, and desire to secure Letters Patent for,is*- 1. In a suspended incandescent electric lamp, the combination withthe lamp-cord of the lam p-shade havin g an insulating-bush secured toit, through which said cord passes; a wire frame, attached to the lampbulb and socket, cooperating with sliding means secured to thelamp-shade, for the purposes as set forth.

2. In a suspended incandescent electric 1o lamp, a frame, constructed ofsuitable material, forming two parallel-running strands and terminatingat each end in two eyes, one eye secured around the apex of the bulb,the other lying around the insulating-bush of the lamp-socket, aninsulating-bush secured to the lamp-shade, having the lamp-cord passingthrough it, means secured to the lampshade wherein the said frame isadjustable,
